Application filed July 5, 1910. Serial No. 570,384.

To all whom it may concern:

Be it known that we, VICTOR E. EDWARDS and JEROME R. GEORGE, citizens of the United States, residing at Worcester, in the county of lVorcester and Commonwealth of Massachusetts, have invented a new and use ful Improvement in Conveyers for Metal Rods, of which the following is a specification, accompanied by drawings forming a part of the same.

, Our invention relates'to that class of conveyers adapted to receive a metal rod from a rolling l'Illll by a longitudinal movement of the rod and to convey the same by a 'sidewise movement, having means for supporting the rods during said sidewise movement and during the period of cooling.

In the present instance we have shown our invention as embodied in a conveyor having a series of stationary supporting bars provided with notches 1n allnement, in which the heated metal rods are supported and straightened during the process of cooling, and a series of movable notched bars by which the heated-metal rods are-moved forward by a sidewise step-by-step move-' ment from one line of notches to the next succeeding line.

Our present invention relates to the means for controlling the movement of the heated rods as they are delivered to the mechanism for transferring them by a s'idewise stepby-step movement, and our invention consists in the construction and-arrangement of parts by which this is accomplished as hereinafter described and pointed out in' the annexed claims. I

In the accompanying drawings Figure 1 represents a side view of a portion of a conveyer embodying our invention. Fig. 2 is a plan view of that part shown in Fig. 1.

Similar reference characters refer to similar parts in the difi'erent figures.

Referring to the accompanying drawings, 1 denotes a series of parallel stationary supporting bars provided with angular notches 2, each set of notches in the bar 1 being arranged in alinement to enable the heated metal rods, as they are moved forward by a step by step movement, to rest in the notches 2. v

3 denotes a series of parallel movable bars having notches 4. The movable bars 3 are carried upon crank plus 5 in cranks 6 which tire length, being only broken by the notches 11, 11 which provide for the movement of the movable bars 3.

In the supporting framework of the conveyer are journaled conical conveyer rolls 12 in alinement with each other and positively driven through a geared connection 13 from a common driving shaft 14. The conveyer rolls 12 are arranged to receive a rod or bar from a rolling mill by ,a longitudinal movement across the peripheries of the conveyor rolls. The upper surfaces of theconveyer rolls 12 project slightlv through openings 15 in the plate 8, to enable the rod or bar to be longitudinally moved by contact with the rolls. As the rolls 12 are conical, their perlpheral speed, and consequently the longitudinal speed of the rods restin thereon, will vary with different planes 0% rotation. The axes of the rolls 12 are substantially horizontal so as to incline the supporting surface of the rolls at a suflicient angle to allow gravity to move the rods sidewise toward the smaller ends of the rolls whenever the rods are released by the stop mechanism hereinafter described.

Journaled in bearings adjacent to the plate 8 are rocking shafts, in the present instance two in number, 1 6 and 17. To the shaft 16ers attached at suitable intervals arms 18, having their free ends bent at substantially right angles and adapted to be extended through openings 19 in the plate 8 and form stops 20 above the plane of the sup orting surfaces of the rolls 12. To the shaft 17 are similarly attached arms 21, with their free ends bent at substantially right angles and adapted to be extended through openings 22 in the plate 8 and form similar stops 23 above the plane of the supporting surfaces of the rolls 12. The rocking shafts 16 and 17 are provided with lever handles 24 and,25, which enable the shafts to be rocked by an attendant for the purpose of bringing the stops 20 and 23 into ment of a rod, in the position indicated by the broken line 27, on the conical conveyer rolls 12.

In the operation of our conveyer a rod is received fromthe rolling mill by a longitudinal movement upon the upper supporting surfaces of the conical conveyer rolls 12, and near their larger ends where the peripheral speed of the rolls 12 is substantially equal to the longitudinal movement of the rod. The stop 20, when brought into the position shown in Fig. 1, serves to prevent the downward' sidewise sliding movement of the rod past the stop 20. At a suitable period in the movement. of the rod the stop 20 is depressed by the rocking of the shaft 16, allowing the rod, which previously had rested against the stop 20, to slide down the supporting surface of the conical rolls l2 and be caught by the stop 23, bringing the rod from the position shown at 26 to the position shown at 27, or nearer the smaller ends of the rolls 12 where the peripheral speed of the rolls is decreased,-

causing a subsequent decrease in the speed of. the longitudinal movement of the rod. The stop'20 is then restored to its normal position, as shown in F-ig. 1, and a succeedmg rod received upon the rolls 12 while the first. rod is still resting upon the rolls 12 and is bein brought by a slow movement to the en of its longitudinal travel, thereby overcoming the momentum imparted by. its quick initial movement. period 'in the movement of the rod, in its position shown at 27, the stops 23 are depressed, allowing the rodto slide downward over the plate 8 into the trough 10, from which it is picked u in the movable bars 3 and carried into the first notch 2 of the stationary bars 1, each succeeding movement of the movable bars '3 carrying the rod by a step-by-step movement across the entire length of the supporting bars 1 until it falls upon the incline'28 and rolls across the skids 29 upon the conveyer rolls 30. 'By the employment of two stop devices the second rod may be-'. entered upon the rolls 12 before the first rod has completed its longitudinal movement, allowing the movement of the rods upon the rolls 12 to overlap each other. The second rod ma therefore be received from the final rolls 0 the millduri the time that the first rod is overcoming e momentum of its %uick initial movement upontherolls 12..

y placing the stop operating mechanism below the plate 8 instead of above it, the

space above theplate'is left free for the At the proper by the notch 4- manipulation of the rods, and the move ment of the stop members 20 and23 is in a plane substantially at right angles to that of the plate 8, thereby avoiding any interference in the respective paths of the rods,
